JBag, nice progress so far.
Russell did jump on you with both feet, and maybe more harshly than I would have done. But the point is a good one that you should make double sure that all the rest of the wiring is done as closely to the NEC as possible. I have worked with dozens of electricians on hundreds of jobs--both remodel and new construction--and one thing I can say is that neat and tidy runs of wiring certainly look professional and many times the rest of the work IS professional (and safe). Often times, a tradesman who takes the time to make his/her wiring, piping, ductwork etc all line up straight, square and neat is the type of tradesman who pays attention to the details where it counts (safety, code compliance).
But I can also think of many, many occasions where professional-looking electrical work was in fact UNSAFE and lacking in many, many critical areas once it came time for the inspector to walk the job.
I don't see the pictures that Russell saw, so I can't comment on anything specific that might have been unsafe. From this point forward, maybe you can hire a local electrician to come in a go over your work at various steps along the way . That will provide an element of safety, piece of mind, and greater chances of success when it comes time for your inspections.
Good luck with the shop project and enjoy the progress you are making.
